Help with tv_grab_es_digital

Hello list, I am trying to recode the old tv_grab_es_digital grabber.
Is from Digital+ satellite provider from spain.

The old code is located here:
http://article.gmane.org/gmane.comp.tv.xmltv.general/1832/

The source data is here:

Basic guide: http://www.plus.es/guiatv/buscadorbasico.html
Advanced guide: http://www.plus.es/guiatv/buscadoravanzado.html

I analyze the basic guide code and this is coded this way:

Days:

id="dia2011-01-17"
id="dia2011-01-18"
id="dia2011-01-19"
id="dia2011-01-20"

Channels:

<label for="c1">1: Canal+</label>
<label for="c2">2: Canal+ DOS</label>
<label for="c3">3: Canal+ ...30</label>
<label for="c4">4: Canal+ Acción</label>

Once I check a day and a channel, I get info on the next page this way:

URL:
http://www.plus.es/guiatv/resultados.html?tipo=dh5&frm=B&dia=2011-01-17&c[]=CP&f=TO&pr=L
http://www.plus.es/guiatv/resultados.html?tipo=dh5&frm=B&dia=2011-01-17&c[]=CP2&f=TO&pr=L

Here is a URL for channel label "c1" (CP) and "c2" (CP2) from the same
day "2011-01-17". On these page there is program start/stop times and
program titles. The description is on different pages.

I think that the first approach is to take start/stop and program title info.

Can someone help with this? I will appreciate any help.

Thanks and best regards.
